You can watch all the period dramas you like, but Keira Knightley and co can't get close to what it must have really been like at Château de Fontainebleau. This sovereign residence for eight centuries was home to all manner of pomp and circumstance. The walls can't talk, but they can show you what it was like during the heydays of French royalty. Get Priority Entrance and avoid the lines (just like the royals would've done).
